Power Window

When the intelligent switching unit (ISU) receives IGN 2 power, the power window relay is grounded by the ISU. When the power window relay is energized, the main driver power window switch, and the motorized ORVM supply operational power to the driver power window switch which has 2 modes, first mode, manual UP/DOWN, and second mode, automatic UP/DOWN.

The power window motor halts automatically in case the motor current reaches 85 percent of the initial starting current while in the UP or DOWN auto mode.

The power window motor also halts automatically in case the switch is pressed to ON again while in the UP or DOWN auto mode.
